首次求救

寻找小铁匠，
期盼回复指点啊

呵呵，好的

谢谢，
是这样解决的

也不能完全说是材料问题
我看了你的K文件，你的冲压方向是U，而dynaform要求的冲压方向是W，所以会导致你说的问题
原因是在dynaform中36号材料缺省的各项异性是在XY面内，如果你的冲压方向不是W向，会出现上述问题，改变局部坐标系即可解决

是材料的问题
已解决

自己顶
期待关注

小铁匠，看了很多你的帖子啊
给点信心我啊，期待你的回复

谢谢各位的回复
dyn mod blk df 文件我已经上传到一楼了
我用的是df5.6
材料是df材料库里的美国型号 ss304 36
料厚0.08mm
用的自动设置，定位我查看过，没有接触
请帮忙查找问题，谢谢了

请把MOD和BLK文件也传上来
*INCLUDE
punch.blk
$
*INCLUDE
punch.mod

:~
1： 使用定位功能确认网格和节点之间没有干涉。
2：确认材料参数的准确性。
3：如果还不行把DF文件发上来，请注明 使用的df的版本。
